2019-03-23SMB3: Fix SMB3.1.1 guest mounts to SambaSteve French1-1/+4
Workaround problem with Samba responses to SMB3.1.1 null user (guest) mounts. The server doesn't set the expected flag in the session setup response so we have to do a similar check to what is done in smb3_validate_negotiate where we also check if the user is a null user (but not sec=krb5 since username might not be passed in on mount for Kerberos case). Note that the commit below tightened the conditions and forced signing for the SMB2-TreeConnect commands as per MS-SMB2. However, this should only apply to normal user sessions and not for cases where there is no user (even if server forgets to set the flag in the response) since we don't have anything useful to sign with. This is especially important now that the more secure SMB3.1.1 protocol is in the default dialect list. An earlier patch ("cifs: allow guest mounts to work for smb3.11") fixed the guest mounts to Windows.

It was mapped to EIO which can be confusing when user space queries for an object GUID for an object for which the server file system doesn't support (or hasn't saved one). As Amir Goldstein suggested this is similar to ENOATTR (equivalently ENODATA in Linux errno definitions) so changing NT STATUS code mapping for OBJECTID_NOT_FOUND to ENODATA.

dedupe_file_range operations is combiled into remap_file_range. But it's always skipped for dedupe operations in function cifs_remap_file_range. Example to test: Before this patch: # dd if=/dev/zero of=cifs/file bs=1M count=1 # xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file XFS_IOC_FILE_EXTENT_SAME: Invalid argument After this patch: # dd if=/dev/zero of=cifs/file bs=1M count=1 # xfs_io -c "dedupe cifs/file 4k 64k 4k" cifs/file XFS_IOC_FILE_EXTENT_SAME: Operation not supported Influence for xfstests: generic/091 generic/112 generic/127 generic/263 These tests report this error "do_copy_range:: Invalid argument" instead of "FIDEDUPERANGE: Invalid argument".

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc fixes from Michael Ellerman: "One fix for a boot failure on 32-bit, introduced during the merge window. A fix for our handling of CLOCK_MONOTONIC in the 64-bit VDSO. Changing the wall clock across the Y2038 boundary could cause CLOCK_MONOTONIC to jump forward and backward. Our spectre_v2 reporting was a bit confusing due to a bug I introduced. On some systems it was reporting that the count cache was disabled and also that we were flushing the count cache on context switch. Only the former is true, and given that the count cache is disabled it doesn't make any sense to flush it. No one reported it, so presumably the presence of any mitigation is all people check for. Finally a small build fix for zsmalloc on 32-bit.

2019-03-22futex: Ensure that futex address is aligned in handle_futex_death()Chen Jie1-0/+4
The futex code requires that the user space addresses of futexes are 32bit aligned. sys_futex() checks this in futex_get_keys() but the robust list code has no alignment check in place. As a consequence the kernel crashes on architectures with strict alignment requirements in handle_futex_death() when trying to cmpxchg() on an unaligned futex address which was retrieved from the robust list.

If a 32 bit allocation request is too big to possibly succeed, it early exits with a failure and then should never update max32_alloc_ size. This patch fixes current code, now the size is only updated if the slow path failed while walking the tree. Without the fix the allocation may enter the slow path again even if there was a failure before of a request with the same or a smaller size.
